The Claim
Five gut bacterial genera—Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister—collectively mediate 14.50% to 18.66% of the association between dietary animal protein intake and bone mineral density at three skeletal sites in Chinese adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In Chinese adults, the gut bacteria Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister account for 14.50% to 18.66% of the link between eating animal protein and bone mineral density at three bone sites.
See the scientific wording
Five gut bacterial genera—Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister—collectively mediate 14.50% to 18.66% of the association between dietary animal protein intake and bone mineral density at three skeletal sites in Chinese adults, suggesting a partial microbial pathway in this relationship.
Eating more animal protein changes the types of bacteria in the gut, and these bacteria produce chemicals that alter how much calcium the body absorbs and how much inflammation is present, which directly affects how much bone is built or broken down.
What the research says
1 studyThis study found that five types of gut bacteria explain about 15–19% of why eating more animal protein might help or hurt bone density in Chinese adults — meaning these bacteria are part of how diet affects bones.
